Nylon was developed by Carothers, an outstanding American scientist, and a research team under his leadership. It is the first synthetic fiber in the world. The emergence of nylon has given textiles a new look. Its synthesis is a major breakthrough in the synthetic fiber industry and a very important milestone in polymer chemistry.
In 1935, a polymer was made from adipic acid and hexamethylenediamine. Since both components contain 6 carbon atoms, it was called polymer 66 at the time. He melted the polymer and squeezed it out through an injection needle, and stretched it under tension to call it fiber. This fiber is polyamide 66 fiber. After industrialization in 1939, it was named Nylon. It is the earliest synthetic fiber variety to achieve industrialization.
English name: Polyamide6 or Nylon6, referred to as PA6; Nylon 6, also known as polyamide 6, is polycaprolactam, which is obtained by ring-opening polycondensation of caprolactam.
It is a translucent or opaque milky white resin with excellent mechanical properties, stiffness, toughness, wear resistance and mechanical shock absorption, good insulation and chemical resistance. Widely used in automotive parts, electronic and electrical parts and other fields.
English name: Polyamide66 or Nylon6; PA66 for short; Nylon 66, also known as polyamide 66, is polyhexamethylene adipamide.
Compared with nylon 6, its mechanical strength, stiffness, heat resistance, wear resistance, and creep resistance are better, but its impact strength and mechanical shock absorption performance are reduced. It is widely used in automobiles, drones, electronic and electrical, etc.
